Abstract | A dual-stage servo system using enhanced active-passive hybrid piezoelectric actuators has been developed for improving existing dual-stage piezoelectric actuators for higher precision positioning and shock resistance, due to the incorporation of passive damping in the design. In this paper, an assembled suspension with three different configurations of microactuators is investigated via shock test and analysis. In the shock test, the assembled suspension with microactuators, which is fixed on a stage mounted on a linear shock machine, is excited under half sine shock impulses provided from the machine. The shock responses are measured by extracting the deformation of the assembled suspension with using a strain gauge attached on it during the shock excitations. The strain responses of the assembled suspension with microactuators are compared to evaluate their shock resistance performances. The experimental and simulation results show the effectiveness of viscoelastic damping layers used in the design of active-passive microactuators. Moreover, the test results also show the enhanced active-passive hybrid piezoelectric actuators would outperform the other cases under the high g shock excitations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
